|SVS is a land surface scheme developed at the Canadian Meteorological Centre (Environment and Climate Change Canada, Dorval, Quebec).|
SVS Version 1.0
Note that the scientific documentation above can be useful to understand the general structure of the SVS land-surface scheme.
However, it refers to one of the first SVS 1.0 versions, and this documentation is not up-to-date with the current SVS 1.0 versions in terms of many equations used in the model.
A new documentation is currently in progress but the 2 files below give an up-to-date overview of SVS 1.0.
This file describes SVS 1.0 prognostic variables (i.e., variables calculated by SVS and which need to be initialized when running SVS).
This picture presents a schema showing the spatial and vertical discretization used by SVS.
SVS Version 2.0
SVS v2.0 is still under development. It is suggested not to use it yet. It includes a multi-layer snow-scheme and the representation of thermal diffusion along the soil column to represent freeze/thaw processes.
How to get the code?
The most recent version of SVS is not yet implemented in recent Standalone MESH releases. In the meanwhile, a version of MESH which includes the latest SVS release can be downloaded here.
